Spraying Colonial-Style Aluminium Windows and Sliding Doors with Black Primer – A Gold Coast Transformation

Why Colonial and French-Style Windows Need Special Attention

Colonial or French-style aluminium windows are some of the trickiest to modernise. Instead of large single panes of glass, they feature grids, bars, and detailed profiles that create their distinctive look. Sliding doors often pair with these windows, carrying the same frame style across larger glass areas.

While the design is timeless, the colours chosen decades ago — usually cream, bronze, or silver anodised — leave homes looking outdated. The bars themselves also cast strong lines across façades, meaning colour choice and precision spraying are critical.

This is where professional spraying with black primer at 28 psi comes in. It’s a process that not only updates the colour but ensures adhesion, durability, and sharp results across detailed frames.

Why Primer and Pressure Matter

When working on colonial-style aluminium windows, two technical details make or break the job:

1. Primer choice

Black primer provides strong coverage under darker topcoats.

It ensures consistent colour depth across thin bars and wide door frames.

It creates the perfect keyed surface for the topcoat to bond with.



2. Spray pressure

At 28 psi, the spray atomises perfectly for aluminium surfaces.

Too high, and overspray builds around the bars.

Too low, and coverage is uneven with texture left behind.




This balance ensures every bar and corner of colonial-style windows is coated cleanly, without drips or excessive build.

Step-by-Step: The RepaintPro Process with Colonial Windows

1. Preparation – The Foundation of Every Job

Full wash-down of aluminium to remove dirt, chalking, and contaminants.

Mechanical sanding to key the surface, paying special attention to grid intersections.

Wax and grease remover applied to ensure nothing compromises adhesion.


2. Masking – Razor Sharpness Across Bars

Glass panes individually masked with precision.

Decking, tiles, and render fully protected.

For sliding doors, track areas taped carefully to prevent clogging.


3. Priming – Black Primer at 28 psi

Norglass All Surface Primer applied in black.

Atomised at 28 psi, producing smooth coverage without excessive overspray.

Bars, corners, and sliding door frames coated evenly, forming a strong adhesion base.

Two coats applied for 60–80 microns total film build.


4. Spraying – Topcoat Application

Concept Acrylic Lacquer sprayed at the same 28 psi.

Each coat builds 25–35 microns dry film thickness.

Multiple coats ensure total 40–60 micron film build for long-term durability.


5. Tape Removal – The Reveal

Precision masking pays off here.

Every bar edge emerges razor-sharp against the glass.

Sliding door edges align seamlessly with window bars, producing a factory-quality finish.

Why Black Primer on Colonial Windows Works So Well

Depth of finish – Black primer under black topcoats gives richer depth.

Bar detail coverage – Bars are narrow; black primer prevents light-coloured “bleed through.”

Consistency with sliding doors – Ensures even colour when small-profile bars meet wide-frame doors.


Without primer — or with the wrong colour — colonial windows risk patchy results that highlight every imperfection.


—

The “Before” – Outdated Colonial Frames

Colonial windows and sliding doors in cream or bronze immediately date a property:

Bars look heavier and more intrusive.

Frames clash with modern renders, roofing, or fencing.

From the street, the entire façade feels stuck in the past.



—

The “After” – Crisp Black Modernism

With black primer and topcoat spraying:

Bars become fine, elegant lines instead of bulky cream grids.

Sliding doors blend into the glass, drawing focus to the view instead of the frames.

Interiors gain contrast, making rooms feel brighter and more modern.


It’s a transformation that doesn’t just refresh the house — it redefines its architectural character.

Why Colonial Windows Need Professional Spraying

Detailed Masking

DIY attempts often fail here. Masking each pane with precision takes time, but without it, overspray ruins the glass.

Correct Film Build

Thin bars demand even spray — too heavy and they drip, too light and they look patchy.

Adhesion and Durability

Without proper primer and pressure, paint peels at intersections where bars meet.

Professional spraying ensures the finish looks crisp on day one and holds up for years in Gold Coast conditions.
